When using the GPS on the Nokia E90 without maps for navigation, the built in software is very basic i.e. you can only go to 1 location and the distance is shown only in km. What I really need the software to be able to create routes of several waypoints and to have the distance showing with options of nautical miles or statute miles. and also to have a user adjustable cross track error. It would also be usefull to have course & track information i.e. the sort of information availiable in most standalone basic GPS units. Of course it would be even better if there were software out there to be able to use the e90 with marine charts. Does anyone know of any software.
